FEED-ROLL FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent in). 654,406, dated July24, 1900. Application filed January 16 1900. Serial No. 1,628. (Nomodel.)

To all whom it may concern:

Be itknown that I, DAVID D. LEWIS, of Lo-' rain, in the county of Lorainand State of Ohio,

have invented anew and useful Improvement in Feed-Rolls forRolling-Mills, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

My invention has relation to'certain new and useful improvements infeed-rollers for rolling-mills, and is designed to provide a roll havinga surface adapted to facilitate the manipulation of the ingot or otherpiece being rolled to properly position the same to enter the respectivepasses of the rolls. As is well known, it is necessary to turn theingotor other piece from side to side or from side to edge to adapt it to thevarious passes of the rolls, this being accomplished by means of devicesknown as manipulators or turners, and which are of various types and errangement. Withsmooth-surfacedfeed-rollers (upon which the ingot lieswhile being manipulated) the ingot is apt to slide on the rolls underthe action of the manipulators instead of turning or rolling on its edgein the desired manner, thus often causing considerable delay in therolling operation. My invention is designed to overcome this difficultyby providing those feed-rolls of the roller-bed adjacent to the rollsand manipulators with a grooved surface, the grooves of which act tocatch and hold an edge of the ingot, and thereby enable it to be readilyturned in the desired manner.

In the accompanying drawings, which illustrate my invention and itsapplication, Figure 1 is a plan view of a portion of a rollingmill,showing my invention applied thereto; and Fig. 2 is a front view of oneof the feedrolls and manipulators, showing the manner in which theinvention operates.

The letter A designates the upper mill-roll; B, the roll table or bed onthe furnace side of the mill; 0, the feed-rolls thereof; D, themanipulators, and E the hydraulic cylinders by means of which themanipulators are actuated.

While Ihave shown the manipulators as being of horizontal type, myinvention is equally desirable in connection with and applicable tomills which employ vertically acting manipulators,

The feed-rolls O are arranged and driven in any usual manner and aresimilar to the ordinary feed-rolls, except that I provide a number ofthem nearest the mi1l-ro1lers with parallel circumferential grooves c,as shown. While I have usually placed these grooves about six inchesapart on the surface of the rolls, measuring from center to center, andhave made themabout one-fourth of an inch in depth, this arrangement isby no means essential, as they may be placed nearer together or fartherapart and may be of any suitable depth. They may also be either ofsemicircular or angular form, and any desired number of the rolls may beprovided with them; The grooves in all the rolls may be alined or everyother roll may have its grooves arranged to alternate with those of theadjacent rolls. The action and advan= tages of the grooves will bereadily understood from Fig. 2, wherein the dotted lines show the ingotI in the act of being turned by the manipulators, the edge-upon which itturns being engaged with a groove of the roll 0, and thereby held fromslipping and sliding. A

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The herein-described feed-roll forrolla ing-mills, having its surfaceprovided with a number of narrow shallow circumferential grooves adaptedto catch the corner of an ingot or other piece being rolled, andseparated from each other by relatively-wide smoothsurfaced portions ofsubstantially-uniform diameter.

2. In a rolling-mill, the combination with manipulators arranged to turningots or other pieces being rolled about their longitudinal axis, ofone or more feed-rolls adjacent to said manipulators whose cylindricalsurfaces are broken at intervals by shallow circumferential groovesadapted to catch and hold a corner of the ingot as the latter is movedby the manipulators.

In testimony whereof I have aflixed my signature in presence of twowitnesses.

DAVID D. LEWIS.
